Which outcome results when freshwater fish experience internal salt dilution?

💡 Explanation

Increased water rushes in because cells suffer from hypotonic shock due to osmosis, where water flows from an area of low solute concentration to areas of high solute concentrations to equalize solutes; therefore, cells uptake water, rather than water expulsion due to being in a hypertonic environment.
